How to solve mingw32-make.exe exited with code 2 error?
提问by Donotalo
I've installed Qt Open source 4.8.3library for Windows on Windows 8 Pro x64, Qt Creator 2.6.0and MingW 4.4.0manually. From Qt Creator I've setup kits and compilers. I opened the analog clock example comes along with Qt Creator and rebuild the project. The following error are emitted by the compiler.
我已经安装了Qt Open source 4.8.3库的Windows上Windows 8 Pro x64，Qt Creator 2.6.0和MingW 4.4.0手动。我从 Qt Creator 安装了工具包和编译器。我打开了 Qt Creator 附带的模拟时钟示例并重建了项目。编译器发出以下错误。

I've verified that C:/Qt/4.8.3/examples/widgets/analogclock/analogclock.cppexists. Besides, this project comes with Qt installation and I didn't change anything.
我已经验证C:/Qt/4.8.3/examples/widgets/analogclock/analogclock.cpp存在。此外，这个项目带有 Qt 安装，我没有改变任何东西。
Why is this error occurring and how can i fix it?

It seems your installation of g++ is not clean, so the compiler cannot be launched (this is also what you've said in the comments). Try reinstall, and then you can try to build a hello world program to verify whether you can run g++. Also, please verify that your PATH variable is properly configured for mingw.
看来您的g++安装不干净，因此无法启动编译器（这也是您在评论中所说的）。尝试重新安装，然后可以尝试构建一个hello world程序来验证是否可以运行g++。另外，请验证您的 PATH 变量是否已为 mingw 正确配置。

Sounds like a bad mingw installation. Are there any other unix-ish things in your %PATH%, i.e. cygwin, or msys, perl, ruby, ... or other versions of mingw?
听起来像一个糟糕的 mingw 安装。您的 %PATH% 中是否还有其他 unix-ish 内容，即 cygwin、msys、perl、ruby 或其他版本的 mingw？
